Benefits of technology

The patent describes a device that helps to keep multiple catheters in place within tissue. This can be done by emplacing the catheters at different angles to the guide structure, or by splaying them out. This makes it harder for the catheters to move or become dislodged from the tissue. Overall, this device helps to provide a more stable and secure placement of catheters in tissue.

Problems solved by technology

The technical problem addressed in this patent text is the difficulty of convection enhanced delivery (CED) of drugs to brain tumors. The current methods of insertion and placement of catheters are not optimal and can result in suboptimal biodistribution of the drugs. The patent text proposes new methods and devices to address this problem by delivering compounds directly into the tumor and sparing normal tissues. The challenge is to determine the optimal placement of the catheters to improve the effectiveness of the treatment.

Embodiment Construction

[0069]The inventive catheter system enables the stereotactic emplacement of a plurality of catheters into a target tissue or field of treatment. The emplacement can be guided by an electronic, radiofrequency, ultrasound, or video-assisted computerized digital navigation and stereotactic system. The individual sources of bioactive agent or drug emanating from each catheter provides an overlapping field of treatment in the target tissue to expose the entire treatment field to an antineoplastic agent, radiopharmaceutical agent, or other pharmaceutical agent. The inventive catheter guidance and guidance system may be used to create essentially any 3-dimensional spatial array of catheters within the target tissue using a catheter guide template, comprising catheter guide tubes or passageways, or both, to guide the catheters into the spatially defined implantation in the target tissue or field of treatment.

Abstract

A catheter system adapted for navigating, guiding and implanting a catheter or a plurality of catheters in a spatially-defined implantation within the tissue of a patient is provided. The system can include a tissue navigation system and a probe to inform the navigation system to guide emplacement of the catheters within a target tissue. The probe can provide images, such as fiberoptic visual images, or ultrasound images, or can provide radiolocation data, to guide the catheter emplacement. The catheters supply a pressurized liquid including a bioactive agent, such as can be used in the treatment of cancer, for example 123I- or 125I-IUDR. The system and methods provided can be used in the treatment of locally advanced tumors, such as cancers of the brain, head or neck, esophagus, prostate, ovary, liver, pancreas, bladder or rectum.
